Default C4 Diagnostic Scanner

What brand/model diagnostic scanner fits a 1990 C4 L98? I bought the Actron CP9001 but it doesn't even begin to match up to the port on the car.
Thanks!

Tech1 and Tech1a were the factory scanners. OTC Monitor 2 and 4000. Snap On MT2500
They are all obsolete and can be found used eBay, Craigslist,....etc. The are OBD1 and require the correct cartridges and accessories to read car.

You need to make sure what ever brand you get it is OBD1 compatible.
